diverting a calibrated portion of bench-supply current around the meter coil so the galvanometer reads heavier loads safely

For timing physics

this 4-inch catch bucket with handle collects water displaced by submerged objects

Low voltage input is via a pair of mounted 4 mm Sockets

the longer focal value softening divergence and producing a wider apparent field through reduced virtual reflections
